Frankly I doubt if this will cause more than a tiny blip in airline travel bookings.
The public is desperate to travel for various reasons and has soon learned to accept all sorts of mechanical and training incidents as the cost of convenience.
Did people stop flying in 747s when cargo doors blew off, did people stop flying in DC10s after a #2 motor broke up disabling all primary flying controls, have people stopped flying with Malaysian after two major losses? Did people stop flying after 9/11?
